[patch] archivers/unzip: -DNO_LCHMOD for Linux, too

[Matthias Ferdinand <mf%14v.de@localhost>]

Hi,

building archivers/unzip on Linux (Ubuntu 14.04 64bit) succeeds, but
produces the following warning:

    ...
    gcc -o unzip  -Lbzip2 unzip.o crc32.o  crypt.o envargs.o explode.o extract.o fileio.o globals.o inflate.o list.o match.o process.o ttyio.o ubz2err.o unreduce.o unshrink.o zipinfo.o unix.o  -s   -L/opt/pkgsrc/lib -Wl,--enable-new-dtags,-R/opt/pkgsrc/lib -lz
    unix.o: In function `set_symlnk_attribs':
=>  unix.c:(.text+0x1840): warning: lchmod is not implemented and will always fail
    ...


The Makefile already sets
    CPPFLAGS+=     -DNO_LCHMOD
for several case of OPSYS.

The attached patch adds Linux to this list.


Regards
Matthias
